“I have been a crane operator for twenty five years. I have been hit by lightening two times while still in the seat. On each occasion we were in a so called “can’t stop” operation. I thank God no one was hurt and I felt no effects whatever myself, but there was cable damage and damage done to other material near the crane on both occasions.

When should the site and crane be evacuated? How to assess the lightning risks? How can the lightning current be safety intercepted and channelled to the ground on a rotating and mobile crane? How to achieve the electrical continuity of the crane structural elements? How to ground properly a tower crane or a gantry crane moving along rails?
